Household Hazardous Waste Collection Facility

In 1997, CCCSD and Mt. View Sanitary District teamed up to build the first permanent Household Hazardous Waste (HHW) Collection Facility for residents of central Contra Costa County. Residents may drop off household hazardous waste at no charge. Small businesses pay a small fee to dispose of their hazardous waste. In its first 15 years, the facility collected more than 26 million pounds of hazardous waste.
